Tillandsias will happily flower and put out babies 'Pups' if given enough bright light and moisture, they are just as happy in a bright kitchen window as they are hanging outside under a tree but they will require simple and consistent care when hung under a roof or in air-conditioning or heating
So hang them in a window where the light is brightest but where the plants will not get burnt by the sun. Or have them outside where they have more shade than sun. Airplants appreciate a little direct morning sun, remember to bring them indoors under 40*f and consistently water them well twice per week in air-conditioning or heating.
The most common way to attach your air plant is by gluing. For this we use ‘Liquid nails’ projects glue available at most hardware stores.
